Plum or pear (5)
I believe the answer is:
fruit
I believe this clue is a double definition.
'plum' is the first definition.
(thesaurus)
'pear' is the second definition.
(thesaurus)
(Other definitions for fruit that I've seen before include "Apples, pears etc" , "Greengrocer's produce" , "Orange, lemon" , "Eg, bananas" , "Kiwi, mandarin etc" .)
